I love the bike. Which I bought with 12k miles+ on the clock from a work colleague who had it from new, mainly in a garage. It is now on 16k, but the bike is currently going through a phase where it slightly struggles/hesitates to respond to throttle (just enought to be frustrating in a teeth crunching way) and the engine noise has also changed to be less smooth for want of a better way to describe this - this has been going on for about 100 miles. I had a simialr probelm aboout 3 months ago when a few hard revs at standstill appeared to clear the problem.

I am reading other posts and there seems alot of talk about coils - I wonder if anyone thinks this is a possible "coils" case and if there is a way to test this without changing them and finally any idea how long it should take a garage to remove fairing, etc and change all three coils.

thanks

Garyn,
Sounds more like a carb problem than coils. When was the last time the carbs have been off, cleaned, inspected, balanced? A 10 year old bike that sits a lot is bound to have a little gunk in the carbs if they haven't been apart. Might be a float valve not seating all the way. Also, make sure the enrichening valve is closeing all the way. Or it could just be bad gas. I would check the whole fuel system first, than check for electrical probs.
Good luck, ride safe
Erv

Just had a similar problem on my 02 1200 Trodent. Drained the fuel, new plugs, cleaned air filer, checked coils and then finally the IJNITION SENSOR.
Turns out thats what it is. It made the bike very hesitant and rough running when it was up to heat,(Half an hour or so.) You would swear it was dity fuel or carbs.
The sensor is a small item which is in the right hand crank cover. It picks up the marks on the rotor. On cars I think you call them a crank sensor.
Unplug the sensor and check the resistance across the termilals, this should be about 350 ohms +/- 10%.
But when mine was hot it went up to 800!ohms. (knackered me thinks!!)
Bought and fitted new one (£40) and she now runs like a good un again.
Might be worth an investigate.
Ive heard of quite a few people complain about rough running Trophys. Usually nipped vacum hose or dirty fuel but I bet a few are down to this pesky sensor!

Read Marks tread about coughing, it sounds to me that you have the same drop and hesitation in revs as he had.

I had the same problem with my 96 30,000miles. Took the carbs off had them cleaned by a local bike shop end of problem.
Hope this helps, good luck.

Honestly, it's a wonder these things run at all! If it's not the vacuum lines, maybe it's the carbs.... no?, try the igniter and then the pick-up sensor. Still having trouble?, check the air filter, the gas tank vent and all of the coils. Oh yeah, it might just be bad gas or the carbs were factory set for high altitudes, and don't forget about the valves. If all else fails check ALL of the electrical connections on the ignition circuit. Remember to put her back together after checking each and every item and make a test run. Then tear back into her if nothing changes. That way the chance of breaking something else increases and before long all of the fairing screws will be stripped or lost(they're 5 bucks each)! And that's if she just isn't running right, if she won't start there's a whole other list!
Did Triumph purposely make these things this complicated? Talk about high maintenance!
I'm budgeting in a complete rebuild the day she starts to sputter, I figure it'll save me 50 hours of frustration in tracking down the problem.
I enjoy maintaining my bike but trouble shooting these things is ridiculous. If Triumph wants a bigger market share they better make their bikes more user friendly.
This is heresy, I know, but a man can buy an Asian bike for the same price(or less) do nothing but change the oil and tires and get 50K miles out of it. Trade her in or sell her and start over again. Time is far more valuable than money.
I want to ride, not wrench.
Sorry for the venting.

Thanks all for comments so far. I almost miss my old Yamaha Diversion 600 which always started, always ran smoothly, did not show close to empty after only 80 or so miles and pretty much kept up with everything in the London traffic.

Anyway I can see this is well beyond my very limited ability to fix and so I have reluctantly booked the bike into a Triumph dealer in Ayelsbury, about 30 miles north of London, and will let them have these comments to chew on when I drop the bike off. To cap it all the earliest they can deal is 3 weeks away.

thanks again

Good luck Grayn
My "cough" would occur during cold temps, but not when warm. This is just the opposite of normal electrical failures.
My problem was a coil. I checked my carbs and yes they were dirty, but not the cause of my problem.
It is very easy to change a coil. You could do it yourself!

If anyone is interested I had the problem sorted by a local motorbike mechanic - he said the carbs were full of gunk and in fact it was only running on 2 cylinders when he got the bike in - anyway £160 poorer but with clean carbs the bike runs really great - and so much better then anytime in the year I have owned it. - but after reading alot of these posts - for how long??
